I'm in the process of setting up a two node MNS cluster for an Exchange 2007 mailbox server. One of the recommendations I came across was to use a different NIC type for the private and public networks so that a driver issue won't take down both interfaces. The servers have on board Broadcom 1G NICS that I would use for the public network communications. I have a number of brand new Intel Pro 100Mb PCI cards and was wondering if those would be suitable to use for the private NIC. Since it's just the heartbeat and housekeeping data on that NIC, and it only connects to the other server (via a crossover cable), would I be causing any issues to use a 100Mb NIC for that? Thanks.

You can also use 10Mb NICs for the heartbeat - heartbeats are small UDP packets so no major bandwidth concerns. -- Bharat Suneja MVP - Exchange www.zenprise.com NEW blog location: exchangepedia.com/blog ---------------------------- "Mike O" wrote in message news:%23J2C11bTIHA.1188@TK2MSFTNGP04.phx.gbl... > I'm in the process of setting up a two node MNS cluster for an Exchange > 2007 mailbox server.

Thanks. That's pretty much what I figured, I just wanted to see if there would be any non-obvious problems..

I probably have a few 10Mb's floating around somewhere, but I think I'll stick to the 100Mb ones. I have about 5 still in their original packaging. So many of the systems are coming with Gb NIC's on the motherboard, we don't use the add on cards much anymore, especially in our datacenter (all the switches are Gb ethernet).
